Is it safe to run this sequence of commands?
hpacucli controller slot=1 array A remove drives=1:8
hpacucli controller slot=1 pd 1:8 modify led=on
get remote hands to remove the drive and replace. Then run:
hpacucli controller slot=1 array A add drives=1:8
Will this get the array to rebuild safely?
Best Answer
It is safe to run those commands. The mirror group can survive the absence of one disk. It should rebuild automatically, but if it doesn't the command you already identified will kick it into gear.
